I would say the answer is <span>dust and rocks
The regolith is a layer of material that covers solid rock. it is made of dust and soil.</span>
To solve number 18 you have to add the positive and negative to equal zero. For example for 18a it would be K2S ( the 2 is a subscript ) because you need 2 positives to cancel out the 2 negatives.
Explanation:
Because molarity is classified as moles of solute per liter of water, dilution of the water may result in a reduction of its concentration.
Therefore, because the amount of moles of solute has to be constant for dilution, you will use the molarity and volume of that same target solution to calculate how many moles of solute will be present in the sample of the stock solution that you dilute.
c = ![\frac{n}{v}](https://tex.z-dn.net/?f=%5Cfrac%7Bn%7D%7Bv%7D)
⇒ n
=
c
⋅ V
= 0.250 M ⋅ 6.00 L =
1.5 moles HCl
Now all you have to do is figure out what volume of 6.0 M stock solution will contain 1.5 moles of hydrochloric acid
c = ![\frac{n}{v}](https://tex.z-dn.net/?f=%5Cfrac%7Bn%7D%7Bv%7D)
V = ![\frac{n}{c}](https://tex.z-dn.net/?f=%5Cfrac%7Bn%7D%7Bc%7D)
=
=
0.25 L
Expressed in milliliters, the answer will be
→ rounded to two sig figs
They use frogs because it easy to get and shows what is going on by what they eat what happened to them and other things.
